SEAL-FASTENING.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed August 14, 1912. Serial No. 714,966.

.set forth, whereby access to the endsof the shackle, secured within the casing cannot be had without breaking a button of fictile material closing said casing and locked therein.

In the accompanying drawingsFigure 1 is a perspective view of my seal fastening. Fig. 2 shows the case in section and the position of the parts while the breakable button is being inserted. Figs. 3 and 4 are similar views, showing the button in locked position, the locking spring in Fig. 3 being in elevation, to exhibit the slit therein.

In Fig. 4 said spring is shown in section. Fig. 5 is a top view of the casing, without the breakable button.

Similar lettersof reference indicate like parts.

The casing A is box-shaped, preferably cylindrical an'dof metal, the rim being bent inward to form the flange B. In the bottom of the casing are holes to receive the ends of the shackle wire 0, which ends, after insgtion, are twisted together, as shown at E is a breakable button, preferably of porcelain or other fictile material, made with a head F and a circumferential groove in its body portion to receive the locking spring G. Said spring has an inclined slit' H in it, and its outer periphery is beveled downwardly. The area of the body portion of the button is of such size as to allow said body portion to enter the opening in the case surrounded by flange B.

In operating the device, the shackle wire is first put in the holes in the bottom of the case and its ends are twisted together, as described. The button is then inserted in the opening, the spring G being compressed so as to close the slit H, as shown in Fig. '2,

The button is ressed inwardly until the spring passes be ow the flangeB, when the spring then expands, as shown in- Figs. 3 and 4. The button cannot afterward be withdrawn because the expanded spring locks against the under side of flange B. The head F covers the joint between the flange and the button, and prevents the introduction of any tool to tamper with the spring.

I claim:

1. A cup-shaped casing, having an inwardly flanged rim, a headed plug having its shank fitting in said rim opening, a locking device on said shank engaging with said rim, and a shackle loop entering and secured in said casing between said plug andthe bottom of said casing.

2. A seal fastening, comprising a cup.- shaped casing, having an inwardly flanged rim, a plug'having a circumferential groove and received in said casing, a spring seated in said groove and compressible to permit the insertion of said plug, and after insertion expanding to engage said rim, and a shackle loop entering-and secured in the space in said casing between said plug and the bottom of said casing.

In testimony whereof I have aflixed my signature in presence of two witnesses.
